What an interesting thread of comments. Good stuff. Here's a link to XIKAR's video on humidification.
http://blog.xikar.com/blog/2010/octo...r-cigars-video View the video and learn more about PG Solution. XIKAR's PG Solution is a proprietary product and manufactured to our exact specifications. XIKAR's mix of PG Solution is calculated to exactly match the rate at which PG biodegrades, resulting in a humidifier that will never over saturate with PG. Other mixtures of PG Solution often contain the incorrect mix, resulting in one of two things: over humidification (not enough PG, too much water) or clogged humidifier (too much PG, not enough water). Either way, those two results ruin expensive cigars. Humidifiers with XIKAR PG Solution emit and absorb just the right amount of humidity in the air to maintain 70% RH. Hope this helps clear the air a little. Keeping smoking and thanks for listening. BM XIKAR
